Dr. Gal Feller

Gal Feller is a medical scholar whose work bridges clinical reasoning, healthcare quality, and oncologic biology. Publications in peer‑reviewed medical journals reflect a strong engagement with conceptual and practical challenges in contemporary medicine, particularly the definitions of health and disease, overdiagnosis, and defensive medicine within clinical practice.

A central research focus concerns cognitive processes in healthcare, including situational awareness, diagnostic error, and metacognition. This body of work analyzes how cognitive biases, system factors, and reflective practice shape diagnostic accuracy and patient safety, offering integrative frameworks to improve clinical decision‑making and reduce preventable harm.

In parallel, contributions to cancer research explore tumour genetic heterogeneity, radiotherapy biology, and mechanisms of treatment resistance in oral squamous cell carcinoma. Additional scholarship on burnout, stress, pain, and executive functioning highlights the neurocognitive and organizational dimensions of clinician wellbeing, underscoring a broad commitment to advancing both patient outcomes and healthcare system performance.
